Low Temperature Radiant Floor Heating The Numerical Simulation And Performance Analysis

Low-Temperature Floor Radiant Heating is a newly developed of heating technology which is comfortable and energy saving.This thesis systematically analyzes the heat transfer phenomena within the Low Temperature Radiant floor, In this thesis, based on the theory of heating transfer, two-dimensional mathematical model for the process of low-temperature radiant floor heating system is set up. Meantime, the determination of initial and boundary conditions of this system obtain a complete mathematical description and controlling equations.Based on the established model, the Finite Difference Method is to be used , the discrete mathematical model is done . A calculating program is developed for the system and get the correct numerical solutions.Second, making use of the calculating results of the program, the influence that the change of external conditions of this system and effect on the parameters is qualitatively analyzed . Then the basic heating regulations are summarized which gives a guideline for system design, construction and operation. By the analysis of the regulations a new calculating way is put forward for the design.At last, based on the mechanism of Low-Temperature Radiant Foor Heating System, describe its thermal comfort, energy efficiency and some other characteristics. Analyzed the economical of the system. Forsees its approaching application in China .It is a kind of heating system with developing prospects and hingh value of popularizing.
